Header not the same in Mozilla/Int Exp

Hi,
I have added a blog to my website and am trying to get it to look as close as poss to my main site.

I have copied and pasted the navigation and logo elements from my main site into the wordpress header and both show up fine. The problem is that they site in completely different places.

I guess I’m looking for anyone who may have had this experience before or anyone who can look at the code and go “ah yes it’s this”. PHP is not really my thing and so I don’t know if I stuffed the coding up or if it’s a problem with tables/divs etc.

Any help would be very much appreciated.

Regards

Andy
